drm/i915: Fix struct mutex vs. RPS lock inversion
RPS lock must be taken before the struct_mutex to avoid locking inversion. So stop grabbing it for the whole powersave initialization and instead only take it during the sections which need it. Also, struct_mutex is not needed any more since dedicated RPS lock was added in: commit 4fc688ce79772496503d22263d61b071a8fb596e Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Fri Nov 2 11:14:01 2012 -0700 drm/i915: protect RPS/RC6 related accesses (including PCU) with a new mutex Based on prototype patch by Chris Wilson and a subsequent mailing list discussion involving Ville, Imre, Chris and Daniel. v2: More details in the commit. v3: Use drm_gem_object_unreference_unlocked.
